Method for using remote sensing images to measure sand wave water depth

The invention discloses a new method for using remote sensing images to measure the sand wave water depth of shallow sea. The new method for using the remote sensing images to measure the sand wave water depth of the shallow sea uses the bright-dark stripe feature information of the shallow sea sand wave terrain presented in the remote sensing images and the quantitative relations among the space position thereof, intensity and sand wave water depth to measure the sand wave water depth of the shallow sea. According to the terrain change monitoring requirement for the broadly distributed shallow sea sand wave regions, by means of the large-scale coverage and high-frequency revisit ability of a remote sensing technology method, the gray data of the remote sensing images are quantitatively processed based on the bright-dark stripe features (comprising the strength and space distribution features of the bright and dark stripes) in the remote sensing images generated by the modulation of the sand wave terrain for the water body flow field and sea surface roughness, and moreover, the gray data are converted through a little of measured data to obtain the sand wave water depth information; the new method for using the remote sensing images to measure the sand wave water depth is used for monitoring the dynamic change of the underwater terrain of the shallow sea, is an innovation for using the remote sensing information technology for the shallow sea water depth measurement, and is very high in practical value.
